The GMD system components at SAFB are operated by the Missile Defense Element of the 100th Missile Defense Brigade. The MDIOC, located at SAFB, contains two GMD fire control and system trainers, which nominally provide for the operational-level command of the GMD system, although the GMD system can be operated from the MDIOC, if necessary. VAFB also includes two relocatable IFCS data terminals. Additional components at FGA include a GMD fire control and system trainer, two command launch equipment sets, and two IFCSs.Īt VAFB, four CE I interceptors are housed among three operational launch facilities, one test launch facility, and one dual-purpose launch facility. At this time, 16 CE I interceptors and 5 CE II interceptors are located at FGA, with most of the interceptors operational at any given time. Plans call for Missile Field 1 to be decommissioned following completion of Missile Field 2. Missile Field 2 with 14 silos is under construction. Currently, Missile Field 1 with 6 silos and Missile Field 3 with 20 silos are operational.

The GBI interceptors exist in two variants, Capability Enhancement I (CE I) and Capability Enhancement II (CE II) the slight differences in software and hardware result in differences in communication range and discrimination strategies.Īt FGA, the GMD system is operated by the 49th Missile Defense Battalion. Once launched, the GBI communicates with BMD through the GMD fire control system using its in-flight communication system (IFCS) twice during the trajectory fly-out. The GMD system interfaces with the BMD C2BMC system that provides target typing and tracks to the GMD fire control system. Ballistic Missile Defense Review Report, Washington, D.C., February.Ĭomponents of the GMD system include the ground-based interceptors (GBIs), located at Fort Greely, Alaska (FGA), and Vandenberg Air Force Base, California (VAFB) the Missile Defense Integrated Operations Center (MDIOC), located at Schriever Air Force Base, Colorado (SAFB) and the GMD Communication Network. Currently, the program is in Phase B (product development), operating with an initial deployed capability. Army Corps of Engineers for construction.
Supplementing the Boeing effort on the booster, subcontractors include Raytheon for the exoatmospheric kill vehicle (EKV) and the sea-based X-band radar (SBX) TRW and Northrup Grumman for command and control, battle management, and communications (C2BMC) and the U.S. The National Missile Defense (NMD) program was established on April 1, 1997, and Boeing was chosen as the lead system integrator (LSI). The GMD program provides a ground-based midcourse interceptor for protection of the United States against ICBM threats. To counter the projected threat from North Korea and Iran for the foreseeable future.” 1 NOTE: blue, operational green, in development purple, being considered red, inactive, terminated, or redirected. TABLE 3-1 BMD Systems Examined in This Report in Terms of Their Potential Mission Applicability Because of continuing improvements in the GMD System and the number of ground-based interceptors now deployed compared to potential North Korean and Iranian long-range ballistic missile capabilities, the United States possesses a capability This is a result of investments made over the past decade in a system based on GMD. The 2010 Ballistic Missile Defense Review Report states that “the United States is currently protected against limited ICBM attacks. PRESENT AND PROPOSED SYSTEMS Ground-Based Midcourse Defense System Specifically, an overview and analysis of the Ground-Based Midcourse Defense (GMD) system the Aegis ballistic missile defense system, with all variants of the standard missile-3 (SM-3) interceptor the Terminal High-Altitude Area Defense (THAAD) system the Patriot (PAC-3) system and the Medium Extended Air Defense System (MEADS) is provided vis-à-vis their potential mission applicability.
boost-phase missile defense as requested in the congressional tasking. This chapter provides additional information on alternative systems to U.S. The non-boost alternatives include the present and proposed systems beyond the boost phase of hostile missile flight-that is, in the ascent or “early intercept” phase, midcourse phase, and terminal phase. boost-phase and non-boost defense alternatives-essentially, present and proposed ballistic missile defense (BMD) systems-that are examined in this report in the context of their potential mission applicability.
